TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed August 10, 1915. Serial No. 44,680.

To all whom it may concern: i

Be it known that I, BUBNHAM C(STICK- NEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type- Writing Machines, of which,the following is a specification.

This invention relates principally to the type-actions of typewriting machines, and one of its main b ects is to produce a simple, inexpensive and compact mechanism suitable for a portable typewriting machine.

The type-barsare relatively short, and pivoted in a short are close to the platen, preferably striking upon the top side of the platen, and normally extending forwardly to a position close to the keyboard and about on a level therewith; thus producing a machine that is of but very little height, and also short from front to back.

The room at the pivots of the type-bars in such a machine is necessarily reduced, and the roo for the mountings and operating mans-is limited. Moreover the keyboard is wider than the system of type-bars, and very much wider. than the length of the pivot-arc of the type-bars, since the latter converge from the types rearwardly to their pivots.

In order to meet all these conditions, I extend the key-levers convergently from the keyboard. and pivot them under the typehars, the system of type-bars and key-levers forming a bank behind which runs the platen, which may be about on a level. with the type-bars. The rear portions of the levers are arranged in the same conver ing )lanes in which the type-bars swing, an the levers are always beneath the ty e-bars, so that no more lateral room is ta on up by the levers than would be needed in any case for the type-bars themselves.

Each type-bar with its lever is pivoted compactly upon an erect thin plate. which constitutes a bracket or hanger; and also pivoted upon said plate is a sub-lever in the form of a bell-crank, which, for lateral comactness, may be connected to the key-lever y a knuckle-joint. These bell-cranks extend upwardly from the key-levers and engage in slots in the type-bars; the plates which form the hangers having a converg lng arrangement corresponding to the radial positions of the type-bars. Each plate may be forked to seat 1n grooves cut in the front and rear sides of the segment; suitable means being provided for locking the hange.

The space-key at the front of the key:

board is mounted to be capable of displacement rearwardly over and back of the keys, to be out of the way when the machine is to be packed up for transportation, thus reducing the bulk.

Other objects and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a diagrammatic side elevation showing a type-action in printing position.

Fig. 2 is a perspective view of a type-bar hanger.

Fig. 3 is a sectional side elevation taken about centrally of the machine from front to rear, and showing the type-actions and appurtenances. I

Fig. 4 is a plan of the machine. F1 5 is a sectional front elevation of type-Ear, sub-lever lhanger and key ley er, showing these four parts .5 closely manged that they occupy the thw isefspaefiif only two P If "ja 7 Upon the top of a sliiftable platen 1, at a point just forward of a line passing vertically through the laten axis, strike types 2, mounted on typeare 8, ivoted at their rear ends at 4 to swing pre erably through nearly half a circle the types normally lying at about the same height as the ke s 5 an nearly on a level with the top of t e platen 1, so that a machine of but little height is produced, and so that the writing will be Each plate, with its,

hangers, each key ots,

upon the forward ends of levers 6 of the second order, which extend rearwardly and terminate forwardly of the platen, being ulcrumed upon studs 7 the platen 1 being in a depressed or sunken position behind the bank formed by the assemblage of key levers and ty e-bars.

The ey levers are connected to the typebars by means of sub-levers, the latter pivoted upon studs 8 and comprising arms 9 extending upwardly and provided with driving wrists or pins 10 to engage slots 11 in the hub portions of the type-burs3 said slots being of great length and curved suitably to accelerate the speed of the typebars during their printing strokes.

In the neighborhood of the type-bar piv it will be observed that there is very owing to the shortness of the the nndesirability of setexcessive angles upon the the assemblage of the bars in as small an are as possible. The typo-bars accordingly. consist of thin blades of sheet metal, mounted upon thin, platelike hangers 1.2, which are erected closely side by side upon a segment 13; the key lever bearings 7 being also fixed upon said hen ers, as well as the sub-lever bearings 8. he hangers, which are converging, may be formed of thin blades; and the typebars may lie against the hangers. The key levers may also extend alongside of the lever directly under its type-bar, sothat no extra lateral room is demanded at this crowded portion of the malittle room, type-bars and to ting the types at bars, necessitating chine for the accommodation of the key levers.

The sub-levers 9 may have short arms 14, connected to the key levers by knuckle joints 15,80 that the sub-levers may also lie against the hangers and just over the key levers, and

beneath the type-bars, so that no lateral room is taken up by the sub-levers. Between their ends the sub-levers may be bent or oil"- set laterally at 16. to occupy the same plane? as the hangers, that is, so that the upper portions of the sublevers will be on the same sides of the type-bars as are the hangers 12. The hangers are rovided with bends at their upper ends 1 to carry the wrists 10, said bends enabling the sub-levers or bellcranks to clear the hangers 12 when in printing osition, asat Fig. 1.

T e sub-levers 9 cross the type-bars, that is, extend upwardly from beneath the typebars to points of engagement at 10 with the type-bars, above the ivots of the latter; the length of each subever from 8 to 10 being in excess of the di stance between 8 and 4.

As will be seen at Fig. 4, the rear portions of the key levers directly underlie and extend along the converging t pe-bars; The key levers extend forward y beyond the typebars, and have outwardly diverging bends at 18, which terminate in parallel forwardly-extending key-bearing portions 19. The key levers work in converging planes, and, owing to the plan of the levers, as seen at Fig. 4, the point of application of power upon each lever is in or very nearly in the plane in which said lever works, so that liability of binding or other faulty action of the lever is reduced or eliminated. In other words, the lever extends forwardly from its pivot along a line which, if extended. would touch or nearly touch its own key; the crossing of the key levers, one by another, being avoided by having the keybearing portions 19 extend substantially in parallelism directly back from the keys, and this arrangement of the key-bearing portions being facilitated by the extra convergleg portions or bends 18 of the levers, between the key-bearing portions and the rear portions that underlie the type-bars.

Each key lever may be bent upwardly at 20 near the segment 13, and downwardly at 21 to underlie the sub-lever 9. The key levers may equal or exceed the type-bars in length. thus avoiding undue slanting of the keys when depressed, without extending back to a position to interfere with the platen or its appurtenances. s

It will he understood that the key lever fnlcrums 7 are arranged in an arc concentric to lhe are of the type-bar pivots 4; and that the sub-lever bearings are also arranged in an arc concentric to said other arcs. The strokes of the sub-levers may be uniform; and the arm 14 may be made as short or as long as required in each case, so as to give the keys uniform strokes. A returning draw spring 22 may extend forwardly from each sub-lever arm 9 to a point of connection 23 to its key lever, so that each hanger, type-bar and lever may be handled as a unit.

Each hanger 12 is formed at its lower portion with forks 24, 25, to bestride'the segment 13, which has on its forward and rear sides downwardly-extending slots 26, to form seats in which the hanger may fit tightly. Each hanger may be locked in place by a locking tongue 27, sprung out,

from the side of a rk, and engaging under a. shoulder 28 formed in the notched portion of the segment. In other words, on the front side of the segment may be upper and lower ribs to form seats for the hen rs, and the ton nos 27 may catch under t e upper ribs. he tongue will spring out when the hanger is pressed down in position, and may be sprung back again by the int of a screw-driver or other tool, when it is desired to remove the he er. The was in the segment may be p aced close y to ther, so that the hangers may be assembl with the necessary compactness; while the entire able points on the levers hanger system forms a very firm, reliable, compact and inexpensive support for the typre-bars, etc.

he segment may be secured by screws 29 upon a crossbar 30, and the latter mabe secured by screws 31 to ears 32 exten ing inwardly from the sides 33 of the type writer framework, so that said bar 30 may be detached from the machine, together with the segment and the entire set of typeactions, bodily. To facilitate this removal, the guide-comb 34 of the key levers is mounted by means of arms 35 and screws 36 upon the forward edge of said bar 30, to be removed or replaced therewith; and upon said guide-comb 34 ma Y be also carried by means of arms 37 a pad or rest 38 for the type-bars, and said arms 37 ma also carry a sto 39 for the key levers -w en in normal positions. Thus, by simply loosening the screws 31, the entire system oftype actions may be readily removed from the machine. i

The platen 1 may be mounted upon any suitable carriage, as indicated diagram matically at 40, and the same Ina have a letter-feeding rack 41, which may e controlled by escapement dogs 42, 43, mounted upon a rocker 44 and havin a returning spring 45, all of conventiona construction. This do rocker may be connected to a universa bar 46 placed. beneath the key levers to remain in the machine when the type-actions are lifted out; said universal ar having a. returnin spring 47. The universal bar may be ma e of considerable extent from front to back, and may be opcrated by any of a series of projections 48 formed upon the under edges of the key levers, said projections being placed at suitto insure that the universal bar 46 shall be given the same stroke by every key.

The universal bar may be carried upon arms 49, pivoted at 50 upon the frame work of the machine; and one of said arms may bear down upon a pin 51 providedupon arm 52, to which is pivoted at 53 the forward end of the link 54, whose rear end is pivoted to the dog-rocker 44; the spring 45 serving to return not only said rocker but also the link 54 and the arm 52.

The space-key 55, arranged in the usual position in front of the keyboard and ex tending along the same, is mounted to be swung upwardly and rearwardly over the keyboard to a position behind the same, as will be seen at Fi 3, to render the machine somewhat less bulky for transportation purposes. For this purpose, the key 55 is mounted upon arms 56, and forms with said arms a bail which surrounds the front por tion of the machine frame, being loosely pivoted upon the ends of pintles 57. The

printing provision of the arms outside of the machine-frame facilitates the swinging up of the ke to the dotted line position at Fig. 3, one ling the bail to clear the various parts in the swinging motion.

When down in working position, the arms 56 bear upon pins 58, which project from pendent arms 59 arranged outside of the machine frame, and fixed upon the outer ends of said pintles 57 the inner ends of the latter being rigidl connected by a bail 60, which at one end rives backwardly a horizontal rod 61, which carries at its rear a tappet 62, to strike the end of the arm 52 and drive back the link 54, to operate the carriage-feeding dog-rocker 44; a returning spring 63 being provided for the rod 61.
